摘要:

带载电磁兼容(electromagnetic compatibility, EMC)试验系统是测试新能源汽车电驱动系统电磁干扰(electromagnetic interference,EMI)性能的重要设备。为优化我国自主研发带载电磁兼容试验系统,推动电驱动系统电磁干扰特性研究,本文优先自主研发了能够完全满足CISPR 25—2016测试标准的电驱穿墙带载电磁兼容试验系统。通过对电磁兼容试验的需求进行分析,提出了电磁兼容试验系统设计方案。然后,建立电磁兼容试验系统三维模型,并进行电磁学仿真,同时对系统的干扰源、屏蔽完整性等进行分析,进而保障所设计系统的电磁兼容性。最后,通过搭建电磁兼容试验系统,基于底噪测试进行分析与优化,进一步提升了系统的准确性与可靠性。

Abstract:

The on-board EMC test system is an important equipment for testing the EMI performance of electric drive system of new energy vehicles. To optimize self-developed on-load EMC test system in China and promote the research of EMI characteristics of electric drive system, this study self-developed the first on-load EMC test system for electric drive through wall that can fully meet the CISPR 25-2016 test standards. By analyzing the demand of EMC test, the design scheme of EMC test system is proposed. Then, a three-dimensional model of the EMC test system is established and electromagnetic simulation is carried out, while the interference sources and shielding integrity of the system are analyzed, so as to guarantee the EMC compatibility of the designed system. Finally, by building the EMC test system, the accuracy and reliability of the system are further improved after analysis and optimization based on the bottom noise test.
